Given numbers are 481, 420, 272, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(481, 420) = 202020
GCD(481, 420) = ( 481 x 420 ) / 202020
= 481 / 420
= 481
Step2:
LCM(1, 272) = 272
GCD(1, 272) = ( 1 x 272 ) / 272
= 1 / 272
= 1
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 481, 420, 272, 790 is 1
